:266 Finding Moisture Pockets

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:266 EcoTip: Thermal imaging using an infrared camera can help identify materials that are wet after flooding or water intrusion. Depending on the nature of the damage – many materials that look dry may in fact be wet. Capillary action and movement of water vapor can cause secondary damage that goes well beyond where the action water flowed. A thermal imaging scan can quickly help identify areas for investigation with a moisture meter. This can help identify pockets of moisture that might otherwise be missed.

This is the eleventh in a series of EcoTips about working around buildings when participating in disaster recovery such as occurred with hurricane Katrina and is going on now with Ike. This information is timely since 2008 is the most active hurricane season since 2005 and many buildings are being damaged.

Today’s 1:5:10:365 Tip for becoming a better steward for our home and planet is about an ecological support business: Thermal imaging.

1:5:10:037 Tip: Thermal imaging camera’s have undergone huge improvements and price reductions in just a few years. When I first began to look at what it would take to use thermal imaging in building investigations 20 years ago, much of the technology was classified by the military. The available units were over $250,000 and required a truck to carry the camera and liquid nitrogen for cooling. Today these camera’s are $6,000 to $20,000 handheld portables that don’t require external coolant. I am partial to the Fluke camera’s and their IR-Fusion technology. This allows a simultaneous digital photograph and thermal image which are superimposed with full blending capabilities. In order to use a thermal imaging camera effectively, thermographers must have training so they learn to “see” and interpret heat instead of light. If you are already in the construction, energy efficiency, insulation, inspection, or moisture control industry it is likely you already have an understanding of buildings that would allow you to easily learn to use a thermal imaging camera to aid you in your work.

Additional Information

It is unfortunate that there have been false claims about thermal cameras and what they can do. What they do is identify temperature differences.

They do not see through walls, find mold, or substitute for a good understanding of buildings and how they work. 

The IR camera is able to find areas for further investigation. Wet walls generally are cooler than dry walls because of evaporative cooling. But a thermographer needs training to tell the difference between missing insulation and moisture.

Today’s 1:5:10:365 Tip for becoming a better steward for our home and planet is about having a thermographic evaluation of your home.

1:5:10:036 Tip: Infra-red thermal imaging is an effective way to scan buildings for missing or damaged insulation, air infiltration, and a variety of other energy wasting conditions.

In order to be most effective the temperature difference between the indoor and outdoor environment should be a minimum of 20 degrees.

***********************************

Additional Information

The yellow/orange/red area shown on the above home is where heat is escaping from this attic. This scan from the exterior of the home demonstrated something was wrong and adding heat to the attic.

It turned out the source of this heat was leaking furnace system duct-work.

Air with a temperature of 147 degrees was leaking from this partially disconnected duct warming the attic and not the house. Sealing this and other areas of leaking duct-work resulted in a winter time gas reduction of over $100 per month.

The US Department of Energy has recommended that home buyers have a thermal imaging evaluation when performing energy audits and when purchasing a new home. They have additional information at:  http://www.eere.energy.gov/consumer/your_home/energy_audits/index.cfm/mytopic=11200

This is best performed during the cold of winter or the heat of summer when the greatest temperature differences can be observed.

If you are looking for someone to perform a thermal imaging inspection of your home, I have listings for Thermographers on my book blog page at:
